title: [Mental disturbances in children and adolescents in Germany. Results of a representative study:age,gender and rater effects].
abstract: METHODS
  A study on behavioral and emotional problems and competence in children and adolescents in Germany (PAK-KID study) is described. It is the first nationwide representative survey of this kind of children and adolescents aged 4 to 18 years in Germany. For children aged 4 to 10 years the parents completed the German version of Achenbach's Child Behavior Checklist (CBCL 4-18) developed by the Arbeitsgruppe Deutsche Child Behavior Checklist. Children and adolescents aged 11 years and older filled out the German version of the Youth Self-Report that is part of Achenbach's CBCL in addition to the parents completing the German version of the CBCL. A total of 2856 parent questionnaires and 1798 self-report questionnaires completed by children and adolescents were analyzed.
  
  
  RESULTS
  The sample was representative with respect to the main sociodemographic variables. On all problem scales children and adolescents aged 11 to 18 years reported significantly more problems than their parents did. The frequency of internalizing problems (social withdrawal, somatic complaints, anxiety/depression) and delinquent behavior of children and adolescents reported by parents increased with the children's age, whereas aggressive behavior and attention problems decreased with age. Girls reported significantly more problems than boys on all internalizing scales of the Youth Self-Report. The effect was not totally replicated in the parent reports. In the parent reports, boys had more attention problems and more aggressive and delinquent behavior than girls.
